I have checked references provided by candidates and I have provided references when asked. Almost always, it is BS because let's face it: Most people wouldn't wanna piss the candidate off and provide either a "they are awesome" or "neutral" reference. For any key hire, I would say go for the backchannels. But be ready for consequences because the candidate may find out anyway. Do what you need to do to find the right person.
